This Is How HBO Filmed That Crazy Battle on the Last Episode of "Game of Thrones"

The most recent episode of Game of Thrones (Stormborn) featured one of the craziest battle scenes we’ve seen yet. Yara Greyjoy was ambushed by her uncle in a massive naval battle resulted in 2 out of the 3 sand snakes being killed and Yara being taken hostage. Oddly enough, the scene was actually filmed in a giant parking lot. Watch the video above to see how the scene was created.
